Description
The LG HE2 is a legendary 18650 lithium-ion cell renowned for its robust power delivery and reliability. Delivering a true 2500mAh capacity and a strong 20A continuous discharge rate, it is a highly cost-effective power source for demanding high-drain devices, including high-power flashlights, power tools, RC models, and high-wattage vaping. This is an unprotected bare cell featuring a flat top design. Available in 2, 4, 6, 8, and 10 pack options to suit your project needs.
Note: This is an unprotected bare cell intended for advanced users and devices with built-in protection circuits. It is overkill for standard low-drain electronics.
Key Features
2500mAh Capacity + 20A Continuous Discharge: Provides robust power for high-drain devices with balanced runtime.
20A Continuous Discharge Rating (CDR): Safely delivers 20A steady current, ideal for high-power flashlights and power tools.
Low Internal Resistance: Excellent heat management under heavy 20A loads.
Flat Top Design: Compatible with a wide range of devices and battery holders.
Unprotected (Bare Cell): No protection circuit, intended for use in devices with built-in protection.
Multiple Pack Options: Available in 2, 4, 6, 8, and 10 packs, perfect for multi-cell setups like dual/quad battery tool pack builds, or bulk replacements.

Applications
High-Power Flashlights: Powers 1500+ lumen tactical lights that require 15A-20A continuous current.
Power Tools: Suitable for small brushless drills, electric screwdrivers, and work lights.
RC Models: Great for 1/10 RC cars and boats needing 20A continuous current.
DIY High-Power Power Banks: Build 2S/4S packs with strong discharge capability.
High-Wattage Vaping: Suitable for regulated mods and mechanical mods requiring high continuous current.
NOT Suitable for: Standard flashlights (<500 lumens), low-drain headlamps, digital cameras, radios, toys, or doorbells (overkill and poor value).
FAQ
Q1: What is the difference between LG HE2 and HG2?
A: The HE2 has a capacity of 2500mAh, while the HG2 has 3000mAh. Both have a 20A continuous discharge rating. The HE2 is typically more affordable for budget-conscious users, while the HG2 offers longer runtime.
Q2: Can I use this battery in a standard flashlight?
A: Not recommended. Standard flashlights (<500 lumens) draw only 0.5A-2A. Using a 20A HE2 is overkill and cost-inefficient. For standard lights, consider 2600mAh or 3500mAh cells.
Q3: Does this battery have a protection circuit?
A: No. This is a bare, unprotected cell. Use with devices/chargers that have built-in over-charge and over-discharge protection.
Q4: Can I use this battery in my power drill?
A: Yes, but primarily for small brushless drills or screwdrivers where the voltage matches (often in a battery pack). For single-cell use, ensure your device accepts a 3.7V flat-top bare cell.
Q5: What are the benefits of the 10-pack?
A: The 10-pack is ideal for bulk purchases, multi-cell devices (e.g., dual/quad battery), DIY battery pack builds, and as a spare cell inventory.
Q6: How many batteries come in one pack?
A: This product is available in 2, 4, 6, 8, and 10 pack options. Please select your desired quantity from the dropdown menu before adding to cart.
